Hello All, testing a single-node O200 SMP with current CVS and the patches from ftp://ftp.linux-mips.org/pub/linux/mips/people/skylark/ , plus the icache flush cache patch from Ralf, plus the PCI detection workaround for ip27 gave - working serial console - working RTC - ethernet with ~2.5 MB throughput and a stable system.
